Is advanced tax refunded if excess, along with itr processing?

Hello All,

I read somewhere that in order to claim excess advanced tax you have to file some form 30 or so?

Is this true?

If after paying advance tax if there's a refund after total computation of tax liability, does IT Dept refund it along with ITR form processing seamlessly to the specified bank account, or does one need to claim it separately?

Regards,

Ram.
